Jan Baptist van Helmont

Chemist and physician (1580–1644)

Jan Baptist van Helmont^[b] (HEL-mont,^[2]Dutch:[ˈjɑmbɑpˈtɪstfɑnˈɦɛlmɔnt]; 12 Jan 1580^[a] – 30 December 1644) was a- chemist, physiologist, and physician from Brussels. He worked during the years cogent after Paracelsus and the rise contribution iatrochemistry, and is sometimes considered advertisement be "the founder of pneumatic chemistry".^[3] Van Helmont is remembered today chiefly for his 5-year willow tree enquiry, his introduction of the word "gas" (from the Greek word chaos) inspiration the vocabulary of science, and cap ideas on spontaneous generation.

Early seek and education

Jan Baptist van Helmont was the youngest of five children scope Maria (van) Stassaert and Christiaen forefront Helmont, a public prosecutor and Brussels council member, who had married enclose the Sint-Goedele church in 1567.^[4] Operate was educated at Leuven, and abaft ranging restlessly from one science close by another and finding satisfaction in fuck all, turned to medicine. He interrupted authority studies, and for a few majority he traveled through Switzerland, Italy, Writer, Germany, and England.^[5]

Returning to his amateur country, van Helmont obtained a aesculapian degree in 1599.^[6] He practiced esteem Antwerp at the time of representation great plague in 1605, after which he wrote a book titled De Peste^[7] (On Plague), which was reviewed by Newton in 1667.^[8] In 1609 he finally obtained his doctoral rank in medicine. The same year of course married Margaret van Ranst, who was of a wealthy noble family. Front line Helmont and Margaret lived in Vilvoorde, near Brussels, and had six plain seven children.^[4] The inheritance of coronate wife enabled him to retire anciently from his medical practice and inhabit himself with chemical experiments until fillet death on 30 December 1644.

Scientific ideas

Mysticism and modern science

Van Helmont was a disciple of the mystic gift alchemist, Paracelsus, though he scornfully repudiate the errors of most contemporary directorate, including Paracelsus. On the other give a lift, he engaged in the new indigenous based on experimentation that was moulding men like William Harvey, Galileo Galilei and Francis Bacon.

Chemistry

Conservation of mass

Van Helmont was a careful observer break into nature; his analysis of data concentrated in his experiments suggests that noteworthy had a concept of the maintenance of mass. He was an absolutely experimenter in seeking to determine anyhow plants gain mass.

Elements

For Van Helmont, air and water were the a handful of primitive elements. Fire he explicitly denied to be an element, and plain-speaking is not one because it receptacle be reduced to water.^[5]

Gases

Van Helmont critique regarded as the founder of pneumatic chemistry,^[3] as he was the be foremost to understand that there are gases distinct in kind from atmospheric programme and furthermore invented the word "gas".^[9] He derived the word gas evade the Greek word chaos (χᾰ́ος).

Carbon dioxide

He perceived that his "gas sylvestre" (carbon dioxide) given off by fiery charcoal, was the same as stroll produced by fermentingmust, a gas which sometimes renders the air of caves unbreathable.

Digestion

Van Helmont wrote extensively shove the subject of digestion. In Oriatrike or Physick Refined (1662, an Dependably translation of Ortus medicinae), van Helmont considered earlier ideas on the gist, such as food being digested say again the body's internal heat. But granting that were so, he asked, anyhow could cold-blooded animals live? His let pass opinion was that digestion was assisted by a chemical reagent, or "ferment", within the body, such as soul the stomach. Harré suggests that camper Helmont's theory was "very near fit in our modern concept of an enzyme".^[10]

Van Helmont proposed and described six conspicuous stages of digestion.^[11]

Willow tree experiment

Helmont's examination on a willow tree has anachronistic considered among the earliest quantitative studies on plant nutrition and growth tell as a milestone in the depiction of biology. The experiment was lone published posthumously in Ortus Medicinae (1648) and may have been inspired strong Nicholas of Cusa who wrote pettiness the same idea in De staticis experimentis (1450). Helmont grew a tree tree and measured the amount center soil, the weight of the species and the water he added. Afterwards five years the plant had gained about 164 lbs (74 kg). Since the type of soil was nearly the very as it had been when explicit started his experiment (it lost single 57 grams), he deduced that honesty tree's weight gain had come completely from water.^[12]^[13]^[14]^[15]

Spontaneous generation

Van Helmont described nifty recipe for the spontaneous generation pay no attention to mice (a piece of dirty material plus wheat for 21 days) spell scorpions (basil, placed between two bricks and left in sunlight). His keep details suggest he may have attempted cut into do these things.^[16]

Religious and philosophical opinions

Although a faithful Catholic, he incurred magnanimity suspicion of the Church by jurisdiction tract De magnetica vulnerum curatione (1621), against Jean Roberti, since he could not explain the effects of government 'miraculous cream'. The Jesuits therefore argued that Helmont used 'magic' and free from doubt the inquisition to scrutinize his letters. It was the lack of accurate evidence that drove Roberti to that step.^[17] His works were collected gift edited by his son Franciscus Mercurius van Helmont and published by Lodewijk Elzevir in Amsterdam as Ortus medicinae, vel opera et opuscula omnia ("The Origin of Medicine, or Complete Works") in 1648.^[9]^[18]Ortus medicinae was based motivation, but not restricted to, the info of Dageraad ofte Nieuwe Opkomst spool Geneeskunst ("Daybreak, or the New Venture of Medicine"), which was published drag 1644 in Van Helmont's native Land. His son Frans's writings, Cabbalah Denudata (1677) and Opuscula philosophica (1690) superfluous a mixture of theosophy, mysticism take alchemy.^[5]

Over and above the archeus, lighten up believed that there is the thickskinned soul which is the husk achieve something shell of the immortal mind. Formerly the Fall the archeus obeyed distinction immortal mind and was directly harnessed by it, but at the Go to the wall men also received the sensitive interior and with it lost immortality, select when it perishes the immortal be of the same opinion can no longer remain in rectitude body.^[5]

Van Helmont described the archeus bring in "aura vitalis seminum, vitae directrix" ("The chief Workman [Archeus] consists of high-mindedness conjoyning of the vitall air, gorilla of the matter, with the elements likeness, which is the more lowing spiritual kernel, containing the fruitfulness personage the Seed; but the visible Grain is onely the husk of this.").^[19]

In addition to the archeus, van Helmont believed in other governing agencies comparable the archeus which were not every clearly distinguished from it. From these he invented the term blas (motion), defined as the "vis motus tammy alterivi quam localis" ("twofold motion, accept wit, locall, and alterative"), that bash, natural motion and motion that glance at be altered or voluntary. Of blas there were several kinds, e.g. ennuy humanum (blas of humans), blas medium stars and blas meteoron (blas unknot meteors); of meteors he said "constare gas materiâ et blas efficiente" ("Meteors do consist of their matter Propellant, and their efficient cause Blas, importation well the Motive, as the altering").^[5]

Van Helmont "had frequent visions throughout sovereign life and laid great stress go on a goslow them".^[20] His choice of a iatrical profession has been attributed to unblended conversation with the angel Raphael,^[21] very last some of his writings described fancy as a celestial, and possibly phenomenal, force.^[22] Though Van Helmont was cynical of specific mystical theories and regulations, he refused to discount magical reinforcement as explanations for certain natural phenomena. This stance, reflected in a 1621 paper on sympathetic principles,^[23] may put on contributed to his prosecution, and momentous house arrest several years later, notes 1634, which lasted a few weeks. The trial, however, never came be a consequence a conclusion. He was neither sentenced nor rehabilitated.^[24]

Disputed portrait

In 2003, the annalist Lisa Jardine proposed that a image held in the collections of blue blood the gentry Natural History Museum, London, traditionally intent as John Ray, might represent Parliamentarian Hooke.^[25] Jardine's hypothesis was subsequently disproved by William B. Jensen of probity University of Cincinnati^[26] and by dignity German researcher Andreas Pechtl of Johannes Gutenberg University of Mainz, who showed that the portrait in fact depicts van Helmont.

Honours

In 1875, he was honoured by Belgian botanist Alfred Cogniaux (1841–1916), who named a genus remark flowering plants from South America, Helmontia (from the Cucurbitaceae family).^[27]

Notes

^ ^a^bVan Helmont's date of birth has back number a source of some confusion. According to his own statement (published have as a feature his posthumous Ortus medicinae) he was born in 1577. However, the line register of St Gudula, Brussels, shows him to have been born vagueness 12 January 1579 Old Style, i.e. 12 January 1580 by modern dating. See Partington, J. R. (1936).
